A Native American elder was walking with his grandson around a lake and forest. They heard some wolves in the distance. The elder said to his grandson: 'There are two wolves that live within me. One is content and happy, and roams around at peace with nature and its surroundings. The other is hungry and ravenous, never satsfied and always looking to destroy and conquer.' The boy looked at his grandfather and asked: 'Which wolf is stronger, Grandpa?' The elder answered: 'It depends on which one I feed.'
